Function First Transmission Mount Upgrade - 911 Carrera Models.

The factory transmission mount was designed for ride comfort and is prone to sagging and tearing – above all, it is a detriment to performance. Its empty voids allow for too much transmission movement, resulting in sloppy handling, numbed responsiveness, and imprecise shifting. Racecars utilize a solid metal mount to mediate this, which is impractical for street use as it transfers extreme noise and vibration into the cabin.

So how do you achieve the benefits of a solid mount while retaining daily drivability? FUNCTION-FIRST Performance offers the only available effective and easy to install solution. The durable urethane rubber insert simply slides in to fill and fortify the empty voids of the factory mount, preventing premature bushing wear and undesirable transmission movement, all while transmitting minimal added noise and vibration.

The result? Handling is taut and predictable; power delivery is immediate and smooth; gear changes are crisp and confident.

This is Function Firsts Orange compound (60A), which is what we recommend for street cars. For daily drivability, or to restore your factory mount with minimal noise and vibration. We consider this the best option for street cars. Other versions are available, contact us if you're looking something more aggressive.

Installation can be completed with basic hand tools in about one hour. Pressing out the stock transmission mount bushing is NOT necessary. Professional installation recommended. Made by Function First, not a factory part.

Fits 911 Carrera models shown, select your year and model.

Please be aware: Although the inserts will help prevent the OEM bushing from tearing, if the bushing is already torn, it will need to be replaced. The inserts serve as a supplement to the bushing, not a replacement. In some cases of extreme bushing sagging, a vise or C-clamp with adequate silicone based lubrication will aid in installation of the inserts. (The 996 series bushings, especially, have a tendency to distort and sag over time.) For 996 GT and Turbo applications, please make sure that you are ordering the correct Insert for your transmission mount. Several customers have found that previous owners with failed OEM trans mounts had them replaced with the 997 unit, and that Transmission Mount Insert design is different compared to the 996 unit.

Increases Firmness
(Knoxville, TN) | June 23rd, 2018
I installed this on my manual trans 97k mile 997.1 Carrera S. Done in conjunction with a trans lubricant change, it only took about 30 minutes to install. Silicone grease or soap, as indicated in the installation instructions, is essential to get the insert in the stock bushing. The result was a very noticeable decrease in the feeling of play or windup in the drivetrain, which translates to a generally more sporting feel. However, there is also a noticeable increase in NVH, especially on throttle overrun at lower engine RPMs. I don't mind this, but be aware that you'll feel it. My car also has new engine mounts from the 997.1 Turbo. Don't know how sloppy mounts might affect the result.
Amazing PDK
(Oakland CA) | November 26th, 2017
I added this product to my 2014 Carrera S (X51 3.8L). First of all I felt an immediate difference in the way the PDK shifted. I now have very clean and crisp shifts even in very high RPMS. Before at high revs you can feel the rough shifting but ever since adding these mount inserts, its gone away. This is a must for any PDK Carrera.
